Super Precision Angular Contact Ball Bearings S71906 ACE/HCP4A

Super Precision Angular Contact Ball Bearings S71906 ACE/HCP4A

The S71906 ACE/HCP4A is a super precision angular contact ball bearing with a 30mm bore and 47mm outer diameter, measuring just 9mm wide. Made from chrome steel with ceramic balls, it offers smooth operation and durability.

This bearing handles radial loads up to 1215 lbf and can reach speeds of 44,000 RPM, thanks to its phenolic cage and sealed design. The 25° contact angle ensures stable performance under angular loads.

Its P4 tolerance class (ABEC-7) guarantees high precision, while the lubricated design reduces maintenance needs. The bearing works in temperatures from -30°C to 110°C.

Ideal for high-speed applications like spindles or precision tools, it’s also available in matched sets for paired use. Weighing only 0.043kg, it’s lightweight yet robust. Interchangeable with SKF bearings for easy replacement.
